Patented Oct. 21, 1947 UNITED STATES PATENT OFFICE AUTOMATIC SPLITTINGMACHINE Irving C. Finkelstein, Brooklyn, N. Y. Application November 3,1945, Serial No. 626,529 7 Claims. (o1.-1c4-s0) This invention relatesto new and useful improvements in an automatic splitting machine.

The splitting machines heretofore known essentially consisted of a tableand means for drawing a web of goods longitudinally thereof. In thistype of splitting machine it is general to manually hold a pair ofshears or other cutter against the moving goods for splitting the same.

This invention proposes an automatic machine for splitting goods whichis capable of splitting the goods to selected widths.

More particularly, the new and improved splitting machine ischaracterized by the provision of a rod transversely mounted of thetable, a platform extending longitudinally of the table and adjustablymounted on said rod, and a motor driven disc cutter associated with saidplatform to do the actual splitting. With this arrangement it ispossible to shift the platform right and left, as desired forcontrolling the width of the pieces split from the web of goods.

Still further the invention proposes a simple arrangement by which thecutter disc may be easily sharpened.

Another object of the invention is the construction of a device asmentioned which is simple and durable and which may be manufactured andsold at a reasonable cost.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

In the accompanying drawing forming a material part of this disclosure:

Fig. 1 is a front elevational View of an automatic splitting machineconstructed in accordance with this invention.

Fig. 2 is a vertical sectional view taken on the line 22 of Fig. 1.

Fig. 3 is a fragmentary enlarged horizontal view looking in thedirection of the line 3-3 of Fig. 2.

Fig. 4 is a vertical sectional view taken on the line 4-3 of Fig. 3, thesection through certain of the parts being shifted to better illustratethe device.

Fig. 5 is a fragmentary sectional view taken on the line 5-5 of Fig. 4.

The automatic splitting machine, in accordance with this invention,includes a table II] provided with means for drawing a web of goodslongitudinally thereof. This means includes a vertical frame I I mountedon the rear of the table H1 and rotatively supporting a friction drumI2.

2 A pulley I3 is connected with the friction drum I2 and is engaged by abelt M. This belt I4 extends downwards along the side of the frame H andengages over another pulley l5 which is connected with a shaft l6provided with still another pulley IT. This latter pulley I! isconnected by a belt l8 to a drive pulley IS. The drive pulley I9 ismounted upon a shaft 20 and controlled with a clutch 2|. The clutch 2|is operated by an adjustable arm 22 which connects with one end of afoot bar 23. The bar 23 is pivotally mounted at its other end upon apintle 24 mounted on the bottom of the table Ill. The shaft 2!! isdriven by a pulley 20' engaged by a belt 29 which is connected with thepulley 25 of an electric motor 26 mounted beneath the table Ill.

The goods schematically illustrated by the dot and dash lines 21 comesup over the front edge of the table l0, then passes over the top of thetable and under a rod 28 which is mounted across the bottom of the frameII. From this rod 28 the goods pass up over the friction drum |2 andthen down to a receiving point.

Up to here the splitting table is more or less conventional. It nowdeparts in the provision of a rod 30 transversely mounted of the table[0, and more specifically, across the bottom of the frame H. A platform3| extends longitudinally of said table [0 and is adjustably mounted onthe rod 30. The platform 3| is formed from a sheet metal piece. It has atop wall 32 and a skirt wall 33 around the edges of the top wall 32. Therod 30 passes through the side sections of the skirt wall 33. Collars 34are slidably mounted on the rod 30 and engage the sides of the skirtwall 33 for holding the platform 3| in selected adjusted positions uponthe rod 30. Wing screws 35 threadedly engage through the collars 34 andabut the rod 30 for holding said collars as desired.

A cutter foot 36 is mounted upon the bottom of the platform 3| and restsupon the top of the table I 0. This cutter foot 36 has a flat bottomportion 31 which is provided with a piece of felt 38 or other padding onits bottom face, so that when resting on the table I!) it does notdamage the surface of the table. The flat bottom portion 31 is rigidlyconnected with a very thin vertical back portion 39 having a knife-likefront edge 43. This back portion 39 connects with a top bracket 4| whichis attached upon the bottom face of the top wall 32 of the platform 3|.

A cutter disc 42 is rotatively mounted above the cutter foot 36, andmore particularly, above the flat bottom portion 31 thereof. The cutterdisc 42 is fixedly mounted on ashaft 43 which is provided with ballbearings 44 mounted in a pair of tubes 45 located to the sides of thecutter disc 42. These tubes 45 are removably attached to the bracket 4!by several fastening screws 43. The shaft 43 is provided with a pulley41 which is engaged by a belt 48 engaging the drive pulley 49 of anelectric motor 50 mounted on the top face of the platform 3|. A belt gard 5! is attached to the side of the skirt wall 33 of the platform 3!and engages over the belt 48 and the pulleys 41 and 49.

The flat bottom portion 31 of the cutter foot" 36 is provided with aslot 52 into which the bottom portion of the cutter disc 42 engages. Thegoods schematically indicated by the dot and dash lines 21 pass over thetop face of the flat bottom portion 37 so as to be split by the rotatingcutter disc 42. The platform 3i is provided with a slot 53 in its topWall through which the top portion of the cutter disc 32'passes. Asharpener wheel 54 is rotatively mounted on an arm 55 which is mountedon a shaft 56 turnably mounted in a pair of standards 51 mounted uponthe top of the platform 3|. The shaft 56 is provided with a projectinghandle 58 by which it may be moved. When the sharpener wheel 54 extendsrearwards it is in an inoperative position. It may be engaged againstthe cutter disc 42 by moving the handle 58 soasto swing the arm 55forwards, as indicated in Fig. 4 by the dot and dash lines.

The operation of the splitting machine is as follows:

When the clutch 21 is open, rotations of the electric motor 26 will notbe transmitted to drive the means for drawing the web -of goods,indicated by the dot and dash lines 21, longitudinally of the table In.The operator may step on the bar 23 which depresses same and through themedium of the rod- 22 indirectly closes the clutch 21. The clutch 2| isassociated with the usual spring, not illustrated, which normally urgesit open, when the rod 23 is released. When the clutch 2| is closedrotations from the motor 26 will be transmitted to rotate the frictiondrum l2, so that the web of goods is drawn rearwards across the tableII), as indicated by the same directional arrows in Fig. 2.

The cutter disc 42 is continuously being driven by the electric motor55. The web of goods passing over the flat bottom portion 31 of thecutter foot 36 will be split by the rotating cutter disc 42. The splitwebs of goods will continue to pass under the rod 28 and over thefriction drum 12.

The line of splitting may be varied by loosening the wing screws 35 sothat the collars 34 are loosened. Now the front of the platform 3l' maybe manually gripped and the platform 3| swung slightly upwards so as todisengage the cutter foot 38 from the top of the table [0. It is nowpossible to shift the platform 3| laterally in one direction or theother any amount for determining the width of the splitting of thegoods. When a desirable position is reached the platform 3| is releasedso that the flat bottom portion 31 comes to rest on the top of the tablein. The collars 34 are then placed adjacent the sides of the skirt wall33 of the platform 3land the wing screws 35 are retightened. A web ofgoods may then be engaged against the disc cutter 42 and thenpassedunder the rod 28 and over the friction drum [2, and the machine is againready to operate automatically.
